GL52LP
LoRa Micro Standby Asset Tracker
The GL52LP is Queclink’s first LoRa integrated product, targeting stationary asset monitoring, inventory control and other tracking management applications that require both a small size and a battery life of over 4 years. The GL52LP is an excellent example of Queclink’s commitment to invest in emerging new technologies. LPWA solutions, such as LoRa, provide a very low power alternative when engaged in battery powered applications. It is equipped with GNSS receiver and motion sensor for location and motion detection.
